FOOT-POWER HAMMER.

SPECIFICATION forming part of Letters Patent No. 417,201, dated December 10, 1889.

Application filed July 11, 1889. Serial No. 317,127. (No model.)

T aZZ whom it may concern: drical lateral extensions (Z, the pivoting of Be it known that I, MICHAEL REDLINGER, said block being accomplished in any desired a resident of Freeport, in the county of Stemanner, but preferably by means of cone 55 phenson and State of Illinois, have invented pointed centers N, passing through the ends certain new and useful Improvements in of the arms 0 and entering corresponding Foot-Power Hammers; and I do hereby desockets in the block D or its extensions (1. clare the following to be a full, clear, and ex- The block D receives and supports one end act description of the invention, suchas will of a hammer-handle E, of any suitable form, ()0 enable others skilled in the art to which it but preferably made up of a single bar of pertains to make and use the same. steel E, bent at its center to form a circular My invention relates to improvements in curve 2, Fig. 2, the two equal parts of the bar foot-power hammers, and is fully described being substantially parallel, and their ends and explainedin this specification and shown being secured in the block D in the manner 65 in the accompanying drawings, in which hereinafter described.

Figure 1 is a perspective view of a hammer On the free end c of the hammer-handle is embodying my invention. Fig. 2 isa view of hung the hammer F, provided at its lower the hammer-head, partly in side elevation end with means for attaching the upper memand partly in vertical section. Fig. 3 is ahoriber f of the two-part die, the curved end e of 70 zontal section through the line X X, Fig. 1, the handle being seated in a socket F, open and illustrates the connection of the main 011 the side of the hammer toward the supstandard and the11aminer-snpportingbracket. porting block D, the inner end of the socket Fig. 4 is a vertical longitudinal section of the being a curve corresponding substantially to pivoted block which support-s the hammerthe outer surface of the curved end of the 75 handle, the plane of the section being through handle. A transverse slot F passes through the line Z Z, Fig.5. Fig. 5 is a transverse the hammer from side to side, the central section of said block, the plane of section beplane of the slot being coincident with the ing through the line Y Y, Fig. 4. Fig. 6 is a" diameter of the curve forming the inner end side elevation of the block which supports of the slot F. A tapered key K is inserted 80 the operating-lever, a portion of the block in the slot F, and passes through the ham 3 being broken away to show its internal conmer and through the open curve at the end struction. of the handle. This key may be driven in In the views, A isa standard or column, of until it slightly expands the curved portion any desired form, provided with a suitable of the handle, and thus binds the handle 85 base, and formed near its upper end with a Iirmly in the socket in the hammer; and it is 3 5 cylindrical neck 0, above which is a head for evident that by this device the hammer may the adjustment of one of the members fof a be adjusted in any desired position within the two-part die. The standard A supports a limits of its angle of oscillation about the horizontal bracket B, formed, preferably, of end of the handle. This adjustment is of 0 asinglebarof iron,bentat its centerin acylingreat importance, as it is absolutely necesdrical curve 1), Figs. 1 and 3, conforming to the sary that the two parts ff of the two-part die surface of the cylindrical neck of the standmake perfect contact when the hammer is ard, the two ends of the bar being extended brought down upon the anvil or head of the from said central curve a suitable distance standard. By means of the construction 5 and at a suitable angle to give the bracket shown this contact is readily secured, as the 5 the necessary size and strength. Upon the key K may be loosened and the hammer outer end of the bracket thus formed is rigidly pressed down upon the anvil until the faces mountedatransverse head 0, formed with upof the dies are in perfect contact, when the wardly-extending arms 0 and downwardlykey may be tightened and the hammer thus :00 extending-arms 0, adapted to support the secured upon the handle in exactly the deoscillating parts of the device. Between the sired position. A second adjustment of ends of the upper arms 0 of the head is pivgreat importance is secured by the connecoted a block D, having preferably non-cylintion of the bracket B and standard A. The

block D.

neck a of the standard being eylindrieahthe rotate the handle slightly in its supportingblock. These movements are provided for by the means illustrated in Figs. 4 and 5, the ends of the two members of the handle beingswaged on a slightly-tapered mandrel and seated in a corresponding socket in the A plug P lies between the two arms and may be moved longitudinally by means a bolt P, provided with a nut P, engaging the end of the bolt and resting against the outer face of a cap or washer \V on the rear end of the block; By means of the bolt and nut the plug P may be drawn outward, soas to tighten the arms within the socket, and thus fasten the handle in any desired position with reference to the block. These various adj ustmentsviz., of the bracket with reference to the standard, the hammer with reference to the handle, and the handle with reference to the bloel -provide completely for the perfect contact of the two members of the two-part die.

Between the ends of the downwardly-extending arms 0 of the head 0 is pivoted a transverse bar G, provided with a forwardextending arm G, whose free end is connected by means of a link L with a point on the head D slightly below and in front of the axis of oscillation of the head. ()n the bar G is formed a block G, in which is secured the upper end of the lever M, adapted to operate the hammer. This lever might be formed upon or attached directly to the bar G; but

I prefer to secure it in the block G in substantially the manner illustrated in Fig. 6, in which R is a channel or recess extending longitudinally through the block and somewhat broader than the lever M, which lies in the channel and is secured by means of a pivot p, passing through the block and lever. Rubber butters g are set in the block near its front end and press against the upper and lower edges of the lever, and a clip g, passing around the block, secures the rubber buffers and prevents their accidental displacement. The rubber buffers being interposed between the lever and the block take up the shock of the blow of the hammer and greatly lessen the strain upon the operator of the machine.

The hammer is held above the anvil in substantially the position shown in Fig. l, by means of a spring or springs S, of any desired form, connecting the block D with the head 0 or with any other stationary portion of the machine, and downward pressure upon the free end of the lever M overcomes the resistance of the spring and swings the hammer downward upon the anvil, the operation of the hammer in this respect being the same as that of foot-power hammers of any ordi- 1'1aryconstruct-ion.

In the use of this hammer, as well as any other heavy forginghammer, it is very desirable to keep the lower die free from scale, and as a foot-power hammer is frequently used in shops not provided with means for furnishing an air-blast, I have found it a great convenience to provide the machine with means for blowing the scale from the die. One simple and practical form of device for this purpose is shown in Fig. 1, in which T is a cylinder of an ordinary air-pump, fastened by any suitable means to the standard A, and T is the piston-rod of the pump, extending downward from the cylinder and provided at its lower end with a horizontal arm extending across and above the lever M, at'a point 'near' the end thereof. The piston may be forced downward by a spring, either within or without the cylinder, and the lever M at each upward movement strikes the extension at the lower end of the piston-rod and forces the piston upward, the air within the cylinder being expelled through a pipe 15, extending upward from the cylinder, and having its upper end so bent 'as to direct the current of air across the face of the die f. Any simple form of pump or bellows may be substituted for the one illustrated and described; but I have found in practice that a pump constructed substal'itially as shown, andwith-out any great accuracy of fitting, works very satisfactorily and keeps the die practically free from scale and cinders.

Having now described and explained my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Ina foot-power hammer, the combination, with a suitable standard adapted to receive one of the parts of a two-part die, of a hammer -supporting bracket supported by the standard and free to rotate about the same, and means, substantially as shown and described, for securing it in any desired position with reference thereto, substantially as and for the purpose set forth.
